具体实施方式Detailed ways
本实施方式提出了一种画面缩放方法，其可以根据用户手指所圈区域大小对显示画面进行对应的放大或缩小动作。该方法适用于各种便携式触摸设备，如手机、便携式播放器、数码相机等。This embodiment proposes a screen zooming method, which can zoom in or zoom out the display screen according to the size of the area circled by the user's finger. The method is applicable to various portable touch devices, such as mobile phones, portable players, digital cameras, and the like.
如图1所示，其为一较佳实施方式的画面缩放方法步骤流程图，包括如下步骤：As shown in Figure 1, it is a flow chart of the steps of the screen zooming method in a preferred embodiment, including the following steps:
步骤S301，记录用户在触摸屏上的画圈操作产生的画圈轨迹。请参阅图2和图3，触摸屏10上分别显示有用户顺时针和逆时针画圈操作产生的画圈轨迹102和104。Step S301 , recording the circle-drawing track generated by the user's circle-drawing operation on the touch screen. Referring to FIG. 2 and FIG. 3 , the
步骤S303，检测画圈轨迹包围的画圈面积。该面积可以按照画圈区域所包括的像素点的数量或触摸矩阵的数量进行计算得来。Step S303, detecting the area of the circle surrounded by the circle track. The area can be calculated according to the number of pixels included in the circled area or the number of touch matrices.
步骤S305，检测画圈轨迹的画圈方向，包括顺时针和逆时针。该顺时针和逆时针分别对应着图像放大和缩小操作。Step S305, detecting the circle direction of the circle track, including clockwise and counterclockwise. The clockwise and counterclockwise correspond to image zoom-in and zoom-out operations, respectively.
步骤S307，计算画圈面积与预设面积的比例关系。本实施方式中，该预设面积为触摸屏的显示面积，以给用户一个直观的参考依据，从而更好的实现用户需要的缩放比例。因为用户顺时针操作更为顺手，且较常使用放大操作，为此，本实施方式中，顺时针对应着放大操作，逆时针对应着缩小操作。Step S307, calculating the proportional relationship between the circled area and the preset area. In this embodiment, the preset area is the display area of the touch screen, so as to provide the user with an intuitive reference basis, so as to better realize the zoom ratio required by the user. Because the clockwise operation is more convenient for the user, and the zoom-in operation is often used, therefore, in this embodiment, the clockwise pointer corresponds to the zoom-in operation, and the counterclockwise pointer corresponds to the zoom-out operation.
步骤S309，根据画圈方向选择放大和缩小处理方式，并根据所述比例关系对显示画面进行放大或缩小处理。所述被缩放的显示画面可以是用户选择的图像或文字，也可以是浏览器显示框，还可以是整个触摸屏显示的界面等。In step S309, the zoom-in and zoom-out processing methods are selected according to the circle drawing direction, and zoom-in or zoom-out processing is performed on the display screen according to the proportional relationship. The zoomed display image may be an image or text selected by the user, a browser display frame, or an interface displayed on the entire touch screen.
使用上述画面缩放方法时，用户只要单手指操作即可实现对所选区域的放大或者缩小，操作简单便捷。上述放大和缩小都属于比例调节的一种，其他实施方式中可以只有放大和缩小功能中的一种。When using the above screen zooming method, the user can zoom in or zoom out the selected area with only one finger operation, and the operation is simple and convenient. Both the zoom-in and zoom-out functions mentioned above belong to one type of proportional adjustment, and there may be only one of the functions of zoom-in and zoom-out in other embodiments.
